Domain of Applicability
The evidence for a relationship between DIO1 inhibition and inflation of the anterior chamber of the swim bladder currently comes from work on zebrafish and fathead minnow.
This KER is probably not sex-dependent since both females and males rely on activation of THs by deiodinase for anterior swim bladder inflation. Additionally, zebrafish are undifferentiated gonochorists, and gonad differentiation starts only around 23-25 dpf (Uchida et al., 2002), after the time point of anterior chamber inflation (around 21 dpf).
